Post subject:  Snow Leopard AppleScript bug?
I have some scripts here, and upt to (and including Leopard), they work fine. In snow Leopard, they fail. This is the kind of code that is causing an error:

Code:
set this_file to "Macintosh HD:Users:paul:Desktop:planet.jpg" as file specification


Yes, the file planet.jpg is on my desktop. I’ve tried it on a Leopard Mac here, and it works. In Snow leopard, it gives an error.

Is this something anyone else knows about and has managed to overcome?

What error does it give?

Sorry. The error is:
Quote:
Can’t make "Macintosh HD:Users:paul:Desktop:planet.jpg" into type file specification.

On my machine, it got rid of "drivename:Users:", it started with the username.

You get the same error with this AppleScript:

Code:
set imageFile to choose file with prompt "Choose an image file to import: "
set imageFile to imageFile as string -- turns it into a string
display dialog imageFile
set myImage to imageFile as file specification


It takes a file you have chosen, turns it into a string, and then tries to turn it back to a file reference. This way, you get a reference to a real file to work with.

Using your code in Snow Leopard gives me the same error you are getting.

Assuming there's a reason why you want it to return a file reference rather than an alias, you can get the same result in 10.6 with something like this:

Code:
set imageFile to choose file with prompt "Choose an image file to import: "
set imageFile to POSIX path of imageFile
set myImage to POSIX file imageFile

HI,
What I am doing is fixing a Freeway Action. The Action takes a file reference from Freeway, drops it in some AppleScript and runs it. The file reference I get from Freeway is not a POSIX file - it’s a colon separated path.

Anyho, the good news is that using as alias instead of as file specification (Which I have just learned was deprecated a while back) seems to fix the problem. Thanks all.

Just need to test pn the other half’s iMac - which is PPC so is running Leopard. If it}s OK on that, I can get an update out. I’d hate to have to start writing Snow Leopard exceptions into the code.... :shock:

Using an alias is almost certainly the best way.

I'll confess I don't know what a Freeway Action is, and not that it matters anymore, but the code you posted was taking the, colon separated, alias reference from the original set > choose file command and turning it into a colon separated file reference. The workaround I suggested would achieve the same thing by taking the alias, colon separated path, turning into a POSIX path and then back again - this time into into a file reference rather than an alias.

Illustration of my rather garbled explanation:
